Answer:
w = 24 1/2
Explanation:
Start with the original problem.
w - 9 1/2 = 15
1.) the question is asking for the solution which means it's looking for what w is equal to. To do this, get w on one side of the equal side by itself to find what it's equal to. In this case, -9 1/2 is in the way of that. So, you'd want to do the opposite of -9 1/2 which is +9 1/2 and do that on both sides of the equation.
w - 9 1/2 = 15
w - 9 1/2 + 9 1/2 = 15 + 9 1/2
(the -9 1/2 and +9 1/2 cancel each other out)
w = 24 1/2
